With their comprehensive performance advantages, basalt fibers are widely used in a variety of industries, including aerospace, defense, transportation, new energy, construction, marine engineering, and petrochemicals. They serve as an upgraded alternative to traditional materials.

Basalt fiber, with natural basalt as its raw material, is formed into a continuous, fine inorganic filament bundle after high-temperature melting, drawing, and heat treatment. Basalt fiber has high-temperature resistance, anti-oxidation, radiation resistance, thermal and acoustic insulation, and excellent filtration performance. Because its production process is clean and pollution-free, it is known as the "21st-century green industrial material." It is then further processed into a composite bar with the form of rebar

Basalt fiber is a continuous filament fiber made from natural basalt rock. The rock is melted at 1450°C-1500°C and then drawn through a platinum-rhodium alloy bushing at high speed. Pure basalt fiber is typically brown. It's a new type of inorganic, eco-friendly, high-performance fiber composed of oxides like silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide. Basalt continuous fiber not only has high strength but also boasts excellent properties such as electrical insulation, corrosion resistance, and high-temperature resistance. Furthermore, its production process generates minimal waste and environmental pollution, and the discarded product can degrade naturally without harm, making it a truly green and eco-friendly material. China has listed basalt fiber as one of the four key fibers for development (along with carbon fiber, aramid, and ultra-high molecular weight polyethylene) and has achieved industrial production. Continuous basalt fiber is now widely used in fiber-reinforced composites, friction materials, shipbuilding, the automotive industry, and high-temperature and protective applications.

In new residential building structures, basalt fiber-reinforced polymer (BFRP) composites are emerging as a highly promising construction material due to their excellent properties, including high strength, lightweight nature, corrosion resistance, and superior seismic performance. 

Although the initial cost of basalt fiber-reinforced polymer (BFRP) composites is higher, their long-term economic benefits in residential construction are significant.

Chopped basalt fiber concrete should ideally be constructed under temperatures ranging from -5°C to 25°C. Both excessively high or low temperatures can lead to an uneven mix.

Chopped basalt fiber-reinforced concrete involves incorporating a certain amount of continuous or discontinuous chopped basalt fibers into concrete using an appropriate method. This approach preserves concrete's inherent compressive strength advantages while significantly enhancing its toughness and tensile strength, thereby effectively reinforcing and strengthening concrete and extending the service life of engineering structures.

Concrete is the most widely used construction material. It offers numerous advantages, including its widespread availability, simple production process, low cost, and ease of application. It's extensively used in various fields such as buildings, roads, bridges, tunnels, and hydraulic engineering. As a large number of engineering projects have developed, the demands on concrete's performance have also gradually increased. Consequently, the shortcomings of traditional concrete, such as insufficient tensile strength, poor crack resistance, and volume instability, have become apparent. Therefore, improving the performance of concrete has consistently been one of the key research directions in civil engineering.

In the field of civil engineering, concrete structures are an extremely important component. However, with the development of the construction industry, the problem of construction waste is becoming increasingly prominent, with discarded concrete accounting for a considerable proportion. To achieve the low-carbon goal of the construction industry, the application of recycled concrete has gradually attracted attention. Nevertheless, recycled concrete has some defects in practical use, such as insufficient strength and poor durability.
